名大の授業：谷村省吾教授「物理学基礎II」第6回　ー　中心力場と保存力場

Picked from a mixed channel: Nagoya University Open Course Ware「名大の授業」 (title sample: Mostly genuine full-length lecture courses and retirement lectures that teach, but mixed with non-teaching department-head interviews, campus marketing (OpenCampus mock lecture), and farewell message videos that should be excluded.; 1 of 3 sampled transcripts read as real teaching); this title passed a strict title check.
